I am using the DMA SPI as slave on a stm32-F401. I use:DMA SPI SlaveHAL_SPI_TransmitReceive_DMA(&hspi2, pTxData, pRxData, len};When I do this a len amount of zeros is written to the FIFO Tx. For my use case I need to write to the Tx buffer using seri...
I bought hundreds of stm32f427vgt6 MCUs, They work abnormally—— The flash size@ address 0x1FFF 7A22 value is 0xFFFF, In theory it should be 0x0400. The MCU uid @ address 0x1FFF 7A10 of the same batch is irregular，but it should be regular accordin...
Hello,I've created a custom PCB with a STM32F207 controller on it. With this board I want to address different targets using SWD. My targets are a STM32F407 and a STM32L431 controller. I implemented a custom SWD interface with Timer and DMA on my F20...
Sending display data to an ILI9341 via SPI. The ILI9341 needs 16bit words in BigEndian. When I convert the STM32 LittleEndian data to BigEndian and then send the data paket as 8bit bytes everything is fine. In order to save the conversion I tried to ...
Hello everyone!Do you guys know how one can establish a connection b/w STM32H7A3ZIQ and a potentiometer X9C103s? Do I need to include a new library for that in the main body of the program? if so, how? Are there any resources I may utilize to establi...
Hello all.I have a custom stm32439VITx board running at 60MHz clocked off the HSI:void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator o...
Hello!I have made an application after viewing a video on the subject, and I could establish aconnection between PC and my app (which is based on a F767 processor, but I don't thinkit matters).On Windows, it's simple. By plugging the device, it's aut...
Things that have tried.Used the GPIO as chip select . In this configuration , the width of chip selected pulse is more than expected. ( Attached oscilloscope short for your reference ).Kindly requesting to sent the procedure or sample code to sent 24...
